First-Bad-Commit : a68c439b1966c91f0ef474e2bf275d6792312726
Comment 3 Andrew 2010-11-12 20:43:22 UTC
So, I should reverse this patch to see if the issue is cleared up?
Comment 4 Dan Carpenter 2010-11-14 18:58:17 UTC
It's not really a bug in a68c439b1966c91f0ef474e2bf275d6792312726, it's a bug in oprofile.  ibs_eilvt_valid() shouldn't be called with preempt enabled.  Robert Richter is the maintainer for that code.

Email him and CC lkml.

(I think the email from Andrew which Rafael quoted was a private email because I can't find it in my LKML inbox).

fix
Comment 6 Andrew Morton 2010-12-21 23:44:16 UTC
maybe a fix, at least.  Unobvious.
Comment 7 Florian Mickler 2010-12-22 07:23:10 UTC
Nice. 

Patch: https://bugzilla.kernel.org/attachment.cgi?id=41192
Comment 8 Thomas Dekker 2010-12-30 21:23:25 UTC
Don't you mean preempt_disable()?
Comment 9 Robert Richter 2011-01-04 11:23:06 UTC
Fix upstream with commit c7c25802b39c443b3745cfa973dc49a97a3491f8.
